• the compounds having the formula I and the pharmaceutical preparations based thereon have, as stated, immunomodulating properties, that is to say they are capable of exerting a favourable influence on the immune system in mammals. They are in particular suitable for therapeutic use in the treatment of auto-immune diseases, such as SLE (systemic lupus erythematosus), rheumatoid arthritis, auto-immune thyroiditis, Sjogrens syndrome, idiopathic thrombocytopenic purpura and haemolytic anaemia.
• the compounds can also be used prophylactically. They can be delivered orally, rectally, parenterally or locally (topically or sublingually), usually in combination with a carrier and other pharmaceutical auxiliaries.
• steroids having the formula I are: 7 ⁇ -stethyl-17 ⁇ -ethinyl-17 ⁇ -hydroxy- ⁇ 5(10) -oestren-3-one, 7 ⁇ -methyl-17 ⁇ -ethinyl- ⁇ 5(10) -oestren-17 ⁇ -ol, 7 ⁇ -methyl-17 ⁇ -ethinyl-17 ⁇ -hydroxy- ⁇ 4 -oestren-3-one, 7 ⁇ -methyl-17 ⁇ -ethyl-17 ⁇ -hydroxy- ⁇ 5(10) -oestren-3-one, 7 ⁇ -methyl-17 ⁇ -ethinyl- ⁇ 5(10) -oestrene-3 ⁇ ,17 ⁇ -diol, 7 ⁇ -methyl-17 ⁇ -ethinyl- ⁇ 5(10) -oestrene-3 ⁇ ,17 ⁇ -diol, 7 ⁇ -methyl-17 ⁇ -allyl-17 ⁇ -hydroxy- ⁇ 5(10) -oestren-3-one, 7 ⁇ ,17 ⁇ -dimethyl-17 ⁇ -hydroxy- ⁇ 4 -oestren-3-one, 7 ⁇ ,17 ⁇ -dimethyl
• the pharmaceutical preparations for use according to the invention can be prepared in accordance with known galenical techniques, for example by converting the relevant steroid compound having the formula I into a form which is suitable for enteral (for example oral or rectal), parenteral (e.g. intravenous, subcutaneous or intramuscular) or local (via the skin or mucous membranes) administration.
• enteral for example oral or rectal
• parenteral e.g. intravenous, subcutaneous or intramuscular
• local via the skin or mucous membranes
• the steroid compound is mixed with or dissolved in a pharmaceutically acceptable carrier.
• preparations are tablets, pills, treats, coated tablets, pastilles, suppositories, powders, (micro-)-capsules, emulsions, suspensions, solutions, implants, ointments, creams and lotions.
• the quantity of active compound ( ⁇ 4 - or ⁇ 5(10) - oestrene derivative according to formula I) in the preparations to be administered enterally is 0.01-25.0 mg and usually 0.1-5.0 mg.

• the effect of the compound to be investigated on the development of the Fabricius bursa is investigated in chicks.
• the compound is administered in the embryonic stage by dipping eggs which have been incubated for three days in an ethanol solution of the compound to be investigated.
• the eggs are thereafter incubated further and ten days after the eggs have hatched, the chicks are killed and the body weight and weight of the Fabricius bursa are determined.
• the Fabricius bursa is an organ which is located immediately next to the cloaca and is responsible for the maturing of the B-cell system, which ensures the production of antibodies.
• the inhibiting action of the compound to be investigated on the development of the said organ is determined, using nandrolone (19-nor- testosterone) as reference.
• nandrolone in another model, the so-called NZB/W model, has an advantageous effect on lupus in NZB/W mice (murine lupus), which is an indication of an advantageous effect of this compound on auto-immune diseases.
• NZB/W mice lupus in NZB/W mice
• the advantageous effect on "murine lupus” does not show any correlation with the hormonal action, namely with the androgenic action in the case in question.
• a difficulty of the NZB/W model is that the tests in this model require such a long time (1 to 1% years).
• the Bursa model is to be preferred.
• NZB/W F-1 hybrid mice spontaneously develop an auto-immune disease with symptoms resembling those of human SLE and also develop Sj ⁇ gren's syndrome-like disorders in the salivary and lacrimal glands. Tibolone inhibited significantly the expression of SLE and Sj ⁇ gren's syndrome-like disorders in the NZB/W mice. For instance, mortality was reduced significantly.
• mice The median survival of female mice increased from 40 weeks (placebo) to 68 weeks with a dose of 0.1 mg/mouse/ day and of castrated male mice from 54 weeks (placebo) to 74 weeks.
• the same dose significantly delayed the development of proteinuria.
• the mononuclear cell infiltrations in the submandibular glands, expressed as the so-called infiltration index, were reduced from about 55 to below 10 in 39 weeks old NZB/W mice. Further, tibolone caused significant reduction of the auto-antibody (anti-dsDNA) levels in the serum of these mice.
